Intelligent textiles of any kind have to be assembled during the final production step. This means that the individual components have to be combined into a final product (e. g. a piece of clothing) using a joining technology. Here traditionally a sewing machine is used. Usually intelligent textiles (in leisure, sports outdoor, protective clothing) are also technical textiles; in this case assembly by ultrasonic is a modern future-oriented and economical alternative to sewing. PFAFF Industrial has been dealing with this technology for more than 25 years.
